Deleting old message when Discord.JS sends new message - discord.js

Question

I'm trying to make a music bot with DiscordJS. It sends a message again when it switches to new music. When it is too much, it causes pollution. How can I set the old message to be deleted and the new message to remain when I switch to a new song or skip a song?
Code:
const { EmbedBuilder, ActionRowBuilder, ButtonBuilder, ButtonStyle, Client } = require('discord.js');
const ms = require('ms');
/**
* #param {Client} client
*/
module.exports.run = async (client, player, track) => {
function capitalizeFirstLetter(string) {
return string.charAt(0).toUpperCase() + string.slice(1);
}
const row = new ActionRowBuilder()
.addComponents(
new ButtonBuilder()
.setCustomId('loop')
.setEmoji(`🔁`)
.setStyle(ButtonStyle.Secondary),
new ButtonBuilder()
.setCustomId('volume-')
.setEmoji(`🔉`)
.setStyle(ButtonStyle.Danger),
new ButtonBuilder()
.setCustomId('p/p')
.setEmoji(`⏯️`)
.setStyle(ButtonStyle.Secondary),
new ButtonBuilder()
.setCustomId('volume+')
.setEmoji(`🔊`)
.setStyle(ButtonStyle.Success),
new ButtonBuilder()
.setCustomId('skip')
.setEmoji(`⏭️`)
.setStyle(ButtonStyle.Secondary),
);
const embed = new EmbedBuilder()
.setAuthor({
name: `Now Playing`,
iconURL: track.info.requester.displayAvatarURL(),
})
.setColor('Blue')
.setDescription(
`
**Track**: [${track.info.title}](${track.info.uri})
`,
)
const channel = client.channels.cache.get(player.textChannel)
await channel?.send({ embeds: [embed], components: [row] })
};
When I switch to the new song, I want the old message to be deleted. I tried removing some lines but it didn't work.

You could store an object that contains channel IDs and message IDs somewhere else in your code:
let songMessages = {
'channel-id-here':'message-id-here',
'another-channel-id':'another-message-id',
// etc
}
Instead of sending a new message at the bottom of your run() function, you could first check for an existing message in the current channel, and if there is one, you can delete it.
// assuming you're able to access the songMessages object globally
const channel = client.channels.cache.get(player.textChannel)
if(songMessages[channel.id]) {
let oldMessage = await channel.messages.fetch(songMessages[channel.id])
await oldMessage.delete()
}
let message = await channel?.send({ embeds: [embed], components: [row] })
songMessages[channel.id] = message.id
You'll have to make sure you remove the data from the object after the bot stops playing music as well.
